Following last year's Shock Trooper and a Shadow Trooper ornaments, visitors to the Hallmark booth at this year's Comic-Con can look for an exclusive K-3PO and R-3PO two-pack (limited to just 1,000 sets), which will be sold in limited quantities each day of the convention. There will also be a limited series of collectible buttons featuring this year's Star Wars Keepsake Ornaments.
